[R] Segmentation fault while using Mclust function of mclust library in R-2.0.1

[Tim F Liao]

Tae-Hoon,

Your code worked with version 1.90:

> Mclust(rnorm(100))

 best model: univariate normal with 1 groups

 averge/median classification uncertainty: 0 / 0 

Warning message: 
optimal number of clusters occurs at min choice in: Mclust
(rnorm(100)) 

The warning should be there because the data you generated 
have only one cluster.  I'm fairly certain it would work 
with R version 2.0 as well which is what I have on my home 
computer and I used Mclust for one-dimensional data last 
month with that version.  If it's a problem with the latest 
version, you can simply download an earlier version of R 
(yesterday there was a thread about where to find version 
1.91 or something like it) and run Mclust with that version.
